19 Claims. (Cl. 189-46) This invention relates to building constructions in general and more particularly to a novel frame or casing construction for insertion in wall openings to support and c0- operate with doors and windows occupying the openings.

Heretofore the formation of frames and casings for doors and windows has required the use of carpenters of the highest skill and rate of pay and further, the mode of casing such openings did not always result in properly hung doors and windows regardless of the skill of the artisan.

With these considerations in mind, it is an object of the present invention to provide a prefabricated casing assembly for wall openings which is readily applied to wall openings and which does not require the use of skill comparable to the skill of the average finished carpenter to install. 1

Another object of the invention is to provide a prefabricated casing assembly for wall openings which may be installed with the component members thereof disposed in true vertical or horizontal positions regardless of the possible departure from plumb or level lines of the edge faces of the openings. 1

A further object of the invention is to provide a prefabricated casing assembly for wall openings which is so constructed and arranged that installation is achieved by a clamping action against the wall faces at each side of the opening.

Still another object of the invention is to provide a prefabricated casing assembly for door and window openings composed of slidably laterally interengaging sheet metal components each of which is provided with a flange or facing portion eugageable with the Wall surfaces at'the opposite sides of the opening.

A still further object of the invention is to provide a prefabricated casing assembly for wall openings comprising separate pairs of interengaging components for the vertical and horizontal sides of the openings and including corner-forming elements effective to hold. the adjacent ends of vertical and horizontal components in cornerforming contact with each other.

Still another object of the invention is to provide a casing assembly attachable to the faces of a wall opening which is so constructed and arranged that it can be readily removed without damage to the wall or to the component parts.

A still further object of the invention is to provide a casing assembly for wall openings in which the major component parts are formed from rolled sheet metal strips with the attendant economy in cost of manufacture.

With the above objects in view, together with such additional objects and advantages as may subsequently appear, the invention resides in the parts, and in the construction, combination, and arrangements of parts, disclosed by way of example in the following specification of certain modes of execution of the invention, reference being had to the accompanying drawings which form a part of said specification and in which. drawings:

Referring first to Figures 1 to 4 of the drawings, the major components of a door opening casing comprise a hinge jamb assembly 1, a striker jamb assembly 2, and a header assembly 3. Each assembly comprises two major elements which will hereinafter be referred to as inner and outer casing elements, the terms inner and outer being used to define the relationship of the edges of the elements at the point at which. they overlap and. with reference to the edge face of the wall opening with the element having the portion thereof closest to the wall at that point being termed the inner element.

These elements are preferably formed from sheet metal strips rolled to form and. both elements may be rolled simultaneously to the form shown. in Figure 4 and be subsequently cut apart at the line X in thatfigure with 3 resultant creation of a bar 4 from which inner elements may be made and a bar 5 from which outer elements may be made by being cut to appropriate lengths and other operations suitable to the use to which the length is put. Each inner element comprises a Wall-engaging edge flange 6, a wall side facing run 7, a wall edge facing run 8, a first lateral run 9 extending away from the edge face of the wall, a second wall edge facing run it) spaced away from the wall edge face by the wi th of the run 9, a second laterally extending run 11 adapted to have holes formed therein for reception of clamping screws to be later referred to, a third lateral run 12 adapted'to engage the side face of the clamping screws, and a third lateral run portion 13 the end of which is adapted to engage the inner face of one of the facing runs of the outer element as will be later described in detail. Each outer element comprises a wallengaging flange edge 14, a wall side facing run 15, a short wall edge facing run 16, a first laterally extending run 17, a hinge-supporting run 15, and a door stop portion 15 comprising an outwardly extending run 26, a tacing run 21 extending parallel to the edge face of the opening, and an inwardly extending run 22 the end of which bears against the outer face of the run is of the inner element.

After being rolled or otherwise shaped to the above described cross-section contour, either as a single piece subsequently cut apart as shown in Figure 4, or separately formed by rolling or bending, the inner and outer memberforming bars 4 and 5 are cut to lengths to form the hinge and striker jamb components and the header components for the desired size of door to be hung and cased thereby. Both ends of the header-forming elements 23 and 24 are cut with outwardly diverging angular faces and the headerengaging ends of the hinge jamb elements 25 and 26 and of the striker jamb elements 27 and 28 are correspondingly beveled to form miter joints with the ends of the header elements as shown at the upper end of Figure 1. Additionally, the run 11 of the elements 23, 25 and 27 is provided with a series of spaced screw thread receiving holes 29, and the run 20 of the elements 24, 26 and 28 is provided with a mating series of punched countersunk holes 30 to receive the heads 31 of a series of clamping screws 32, the threaded portions 33 of which engage the holes 29 in the run 11 of the inner elements.

The run 17 of the outer elements 26 of the hinge jamb assembly near the upper and lower ends thereof is provided with rectangular slots 34 through which the leaves 35 of one side of a pair of hinges 36 are inserted with the shoulder portion 37 engaging the face of the run 17. The hinges are secured to the under face of the run 18 by screws 38 which extend through holes in the run 13 and mating holes in the hinge leaves 35 and threadedly engage holes in a washer plate 39 on the opposite face of the hinge leaves, as best shown in Figures 2 and 3. The washer plate is provided with a laterally offset flange edge 40 which engages the corner formed by the juncture of the runs 16 and 17, and is further provided with a tongue portion 41 which engages a mating groove 42 in the face of the hinge leaf which operates to draw the hinge leaf into alignment with the face of the runs 1'7 and 18 and with the other hinge or hinges mounted on the hinge jamb component, it being understood that while only a pair of hinges are here shown, in those instances in which the weight of the door requires it, one or more additional vhinges may be used.

The striker jamb assembly comprises an inner element 27, which is identical with the inner element 25 of the hinge jamb assembly, and an outer member 28 formed from the bar Section 5, having mating clamp screw holes but having the hinge leaf-receiving slots omitted. At the level of the door latch the run 18 is provided with an inwardly struck tongue 43 forming a latch-receiving opening 44, and in the run 16 adjacent the juncture with the run 16 the member 28 is provided with a narrow slot 45. Mounted in the opening 44 and slot 45 and extending between them is a strike plate 46 formed of hard, resilient metal including a foot portion 47, a run 43 extending at right angles to the foot portion, a run 49 extending parallel to the run 18, a shallow return bend portion 50, and a free end portion 51. To assemble the strike plate to the member 28 the foot portion 47 is first inserted in the slot 45 and the plate is then rocked clockwise as viewed in Figure 8 until the end of the run 48 enters the slot 45. The free end 51 is then sprung outwardly sufliciently to enter the opening 44, and the strike plate is then rotated further until the run 49 engages the face of the run 18 and the return bend portion engages the edge of the opening 44, as shown in Figure 8, to lock the strike plate in place.

The miter corners formed by the juncture of the hinge and striker jamb assemblies with the ends of the header assembly are maintained by a corner-aligning means comprising a pair of slidingly interengaging members 52 and 53, best shown in perspective in assembled and disassembled relation, respectively, in Figures 14 and 17. In transverse cross-section the shank portions 54 and 55 of these members are generally L-shaped with the shank 54 of the member 52 disposed within the angle of the shank 55 of the member 53, the side edges 56 of the shank 54 being slightly outturned in opposite directions and slidingly engaging mating grooves 57 formed in the side edges of the shank 55, as best shown in Figure 15. The outer faces of the shank portions rest against the corners of the wall opening being cased and the inner faces rest against the inner faces of the header elements and the hinge or striker jamb elements. The member 53 at its outer end is provided with a generally right angled flange head portion, one portion 58 of which fits in the space between the ftange 6 and run 8 of a header member 23, and another portion 59 which fits between the tlange 6 and run 3 of a jamb element 25 or 27 depending on the corner to which it is applied. The-member 54 at its outer end is provided with corresponding flange portions 69 and 61 which correspondingly engage the space between the flange 14 and run 16 of a header element 24 and of a hinge or striker element 26 or 28.

In installation a hinge jamb assembly comprising inner and outer members 25 and 26 loosely connected .by screws 32 and having a corner-aligning assembly comprising an interfitted pair of members 52 and 53 mounted at its upper end is placed over the wall at the hinge side of a door opening and loosely engaged with the wall by tightening of the screws 32. The assembly is then moved to an exact plumb position with the use of a level and fixed in position by a final tightening of the screws 32 which draw the members 25 and 26 toward each other causing the flanges 6 and 14, to engage the sides of the walls tightly. A header assembly comprising members 23 and 24 loosely connected by screws 32 and having a corner-aligning asssembly mounted in the end thereof opposite the hinge jamb assembly is positioned at the upper edge of the door opening by moving the end of the header assembly over the end of the corner-aligning assembly carried by the hinge jamb assembly and the header assembly is lightly secured in place by tightening the screws 32 associated therewith. The striker jamb assembly is next placed over the opposite side of the door opening by moving the upper end thereof over the depending end of the corner-aligning means carried by the end of the header assembly and is also lightly tightened in place by its clamp screws 32. The door D is then hung on the hinges 36 and the door swung to closed position. The header and striker jamb assemblies are then adjusted toward or away from the edges of the door to provide the desired operating clearance, the door swung to open position to afford access to the screws 32 of the header and striker jamb assemblies, the screws 32 associated therewith are tightened and the mounting of the casing and door is complete. While the above casing may be used with any door ofa mating size having its portions of the hinges and a lock applied thereto before mounting, the casing of the present invention is particularly desirable in situations such as useful; when used with a door such as described and claimed inmy Pendingapplication for patent, Serial No. 223,728; filed April 30, 1951. Also, while the illustrated form. of the invention shows a striker plate for a latch bolt lock, it will be appreciated that the striker plate jamb component may be equipped for other types of door-locking means where desired.

Theresulting installation is readily made and when the; door is closed there is no evidence of the attaching means, since the exposed heads of the clamping screwsare then concealed. It will be apparent that when andif it is desired to remove the door and casing from the opening, such removal is readily accomplished by firstaremoving the door from the hinges and then loosening the; screws 32. The casing and door are then available for other installation. This feature is especially in oifice buildings where partition and room arrangement changes are constantly being made to suit the needs of the various tenants.

The above described embodiment of the invention is that! which is adapted for the most general use and is satisfactory for walls ofthe. usual thickness and surface, say, up to about 4 inches thick and having a plaster or wallboard. or; equivalent smooth surface. Since the Clamping screws are disposed outwardly from the edge surface of the wall opening, upon being tightened these screws will have a tendency to how the overlapping portions. of the. casing components inwardly toward the opening surface, but this tendency is resisted by the engage ment. of the side of the run 12 of the inner member of the component with the side. of the threaded body of the screws 32 and by the engagement of the. end of the run 13 of the inner member with the inner face of the run 21 of the outer member as. well as: the engagement of the end of the run 22 of the outer member with the outer face of the run, of the inner member, as will be apparent by referenceto Figure 3.

For walls having a rough or uneven surface and on which the edges of. the flanges 6 and 1d are liable to get insutncient grippingagainst the wall an auxiliary wallgripping means is employed, a desirable form thereof being illustrated in Figures 11, 12 and. 13. The wallgrippihg units each comprise a pair of members 62 and 63 adapted to be inserted between the casing and the portions of the wall and opening covered by the casing. The member 62 is associated with the inner member of the casing. component and comprises a head 64 adapted to be contained within the shallow U-shaped channel formed by the flange 6. and runs 7 and 8 of the inner member, a shank portion 65 extending along the inner face of the run 8 and a thicker end portion 66 lying in thespace beneath the door stop and clamping screw portions of the casing component elements, said thicker portion having a pair of longitudinally extending oppositely disposed ribs 67 engageable with mating grooves 68 in the adjacent end of the member 63. The. member 63 includes a headportion 69 adapted. to be received in the shallow U-shaped channel in the outer member of the casing components formed by the flange 14 and the runs and 16 thereof and ashankportion 70 which extends from the inner face of the run 17 along the inner face of the run 18 and thence into the space beneath the door stop and clamping screw portions of the casing components terminating in a socket portion 71 in the inner face of which the grooves 68* are located. The wall-engaging sides of the heads 64 and 69 are provided, respectively, with spaced ribs 72 and 73 extending transversely to the length of the casing and which, under pressure applied to the members by action of the clamping screws 32 on the casing members, engage the wall surfaces with localized transverse line contacts which because of the shorter length are. more tightly engaged with the wall. These wall-gripping units are inserted in the loosely assembled casing components before application to the wall opening and as many are used as needed. In general, the number required does not exceed more than one of such units for each. clamping: screw, but the actual number may be varied to suit individual situations.

Where theinvention is to be applied to thicker walls such as solid concrete or concrete block or brick walls, a different mounting accessory such as shown in Figures 18' to 21, inclusive, is desirable. For such installations the general contour of the casing component elements is the same but the wall facing runs 7 and 15 thereof may be somewhat wider and the difference in wall thickness is accommodated by a corresponding increase in the length of the run 10 of the inner element 5, as best shown in Figure 19. The accessory mounting means 74 comprises a narrow strip of hard spring steel having the ends 75 thereof bent at a right angle in the same direction at a distance apart which is slightly in excess of the thickness of the wall and the ends 75 are thence bent outwardly slightly to engage. the corners of the casing; elements formed by the juncture of the flanges 6 and 14 with the runs 7 and 15 as shown in Figure 18. Adjacent each end the strip is provided with struck out pointed tongues 76 adapted to be driven into the edge face of the wall to install the mounting means thereon prior to application of the casing assemblies thereto. Also, at its mid point the strip is provided with a shallow outwardly extending return bent portion 77, the outer face of which engages the inner face of the run 10 adjacent to the clamping screw area and supports the members against being bowed in towardv the wall edge face incident to tightening of the clamping screws 32. The form of the accessory shown in Figures 20 and 21 is particularly adapted for use. on openings in brick walls, the tongues 76, thereof being slightly shorter andhaving a base width which is approximately equal to the thickness of the mortar between. adjacent bricks, as shown in Figure 21. Also, as shown in Figures 20 and 21, the length of the tongues 011 each mounting member may be slightly different to enable installation by first starting one of the tongues into the wall structure. This modification may alsoybe employed with the form of mounting means shown in Figures 18 and. 19..

The installation of the casing with this second modification is. preceded. by the installation of the desired numv ber of mounting elements, after which the attachment of the casing components proceeds in the manner previously described.

Thus there has been created a casing and door means which is, susceptible of economical manufacture and installation and which, further may be readily removed and rte-installed without damage to either the wall or the casing and door other than the slight scars left by the mounting accessory shown in Figures 18 to 21 in the case of thick walls. The invention further is not limited in usefulness to doorways since it will be apparent that the clamping principle is equally well adapted to use in connection with window casings and it is to be. understood that in the claims hereinafter set forth, those claims which are not specifically limited to doorways or door casings are to be construed as including window casings as Well. It is appreciated that window casings employing the principles of the present invention are necessarily of somewhat different form to allow the mounting of windows therein and to provide weather seals at the exterior face thereof, but the mode of attachment of the inner and outer elements of the. casing com.- ponents will be the same as. employed for the door casing components.

While in the foregoing specification I have described and illustrated certain modes of execution of my inven-v tion, I do not intend that this invention shall be deemed to be limited to the specific forms. so. disclosed, and I declare that the invention embraces all such modifications in the parts and in the. construction, combination, and. arrangement of. parts as shall come within the pur view of the appended claims.
